M. Reza Ayromlou
Computational Astrophysicist
Argelander Fellow at the University of Bonn — galaxy formation, large-scale structure, and cosmological simulations. Working on galaxy formation and evolution, large-scale structure cosmology, and cosmological simulations
My Research
Galaxy formation and evolution, studied through large cosmological simulations.
Numerical Simulations
Large cosmological hydrodynamical simulations and semi-analytic models — iCluster, FRONTIER, and L-Galaxies — used to model the Universe across cosmic time.
Closure Radius
How far feedback pushes baryons beyond a halo, and the radius at which the baryon budget closes again — from dwarfs to massive clusters.
Galactic Conformity
Why the properties of neighbouring galaxies correlate over large separations, and what that reveals about the physical processes behind it.
Environmental Processes
Ram-pressure stripping, tidal effects, mergers, assembly bias, and the gas flows that shape halos and galaxies.
High-Redshift Universe
Galaxy populations and scaling relations in the early Universe, and how they connect to what we observe today.
Selected publications
Three papers that best represent my work.
Latest news

iCluster awarded 20 million CPU hours
The iCluster simulation project was awarded 20 million CPU hours on the LRZ supercomputer.
iCluster simulations complete
The full iCluster simulation suite has finished running, and analysis is now underway.

I am the Argelander Fellow at the University of Bonn, based in Bonn, Germany. Before Bonn I was a postdoctoral researcher at the Center for Astronomy of Heidelberg University, following a bridging postdoc at the Max Planck Institute for Astrophysics, where I completed my PhD in 2021 together with LMU Munich.
I develop and analyze cosmological simulations to understand how cosmic structures and galaxies form and evolve.
